Any phone with a bad signal strains to maintain the connection, which can eat away at battery life, there is the relevance.

You’ll see “low signal” when you are using service in a poor reception area. When the phone needs to search for a signal all the time it uses more battery life. We normally see this on Home & Lock Screen and Personal Hotspot. The best thing to do to save battery in these situations is look for a way to get a better signal, or maybe even turn cellular off ...

This is a bug in apple diagnostics. Your battery has to be fully charged (green magsafe led) when running the test to prevent that error. The error appears only in the ONLINE version 1.0.10r2. The original OFFLINE version 1.0 that came with your MBP is working correctly. Don't worry about the adapter it's normal that it heats up, nothing is wrong with ...

In my experience one of the worst things for a battery is to leave it plugged in and not cycle it. After doing this for a few months most batteries seem to become useless, sometimes not even keeping a charge for 5 minutes.

There are 3 main factors that age a battery. One is of course the constant charging and discharging.- the more the faster. Second one is less know and it is the shelf life. Even if you do not use a battery it will eventually die due to the internal currents / shelf life. Third and worse is Charging at all times in a elevated temperature environment. In ...

I can speak from experience that the battery from by 2011 MBP 13' died (like only 10% of designed capacity left) after 56 cycles. It met a precipitous decline after a certain point. You may want you weigh your risk on the cost of replacing the battery.

That shouldn't happen at all. I think the battery itself has a defect. Because the battery wasn't charged before you got it, for a much longer time than two weeks. Because, the seller has, obviously, stored the battery himself for a long time. I would recommend to return the battery immediately. Otherwise you risk damage to your laptop.

It should not be on a "new" MBA but it is possible. Reset your SMC (System management Controller) that has to to with Battery and charging. Shut down the computer. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected. On the built-in keyboard, press the (left side) Shift-Control-Option(alt) keys and the ...

I had a battery replaced on the day after iPhone 6 launch and the process took 50 minutes door to door. (Entering the store to leaving). We did have a reservation and chose to stay past the "50 minutes" to let the iCloud restore finish and get key apps from the in store cache / fast internet. I would expect you might get in and out 10 minutes quicker on a ...

There was a pretty good study done on this specific question done here. Also, it's important to note that Apple's stated battery life is based upon very light workload tests. http://www.anandtech.com/show/7113/2013-macbook-air-core-i5-4250u-vs-core-i7-4650u/4 Key take aways Idle/light workload battery time is nearly the same Medium and heavy workloads ...

Not a real answer, but a fair comparison... I have a 10-year old iPod [iPod photo, I think] that lives in my car glove-box, hooked up to power & connectivity on my car audio system. It only gets used when I'm driving. When I'm not out & about it gets no power, sometimes up to 2 weeks at a time. I bring it into the house & update it from iTunes ...

No. This A1322 model battery fits many MBP 13's, all the way back to 2009 version. Given the number of iterations and countries MBP have been sold, it's due to have different part numbers. I also have a MBP 13' Early 2011 version. Two months ago I replaced the battery with a A1322 battery I bought online and I haven't had a problem. Beware that: If you ...

Nobody can answer that with 100% certainty. We do not know your workmanship skills, and if you made any errors. You could charge the battery without the screen connected. Using the Computer to charge it is safer anyway since the current from computer is limited and less then from the charger for what ever is it worth.

I have the exact same model and had the same issue. Originally, I took the generic troubleshooting steps (reset SMC, unplug let sit, etc.). Didn't work. I then used isopropyl alcohol to clean both the magsafe adapter pins and the magsafe input on the machine. Ran the test again (multiple times) and no error occurred. This was a temporary solution. A few ...

I fixed this problem by deleting my iCloud account on my phone. Then i set up a new rule in my mail so that any mail coming in to my iCloud account got automatically sent to another email account (which i have on my phone) this is a temporary fix until apple sorts this out. Its not ideal but it works for now..

Everytime we unplug the power, Mac will start to discharge the battery. In this manner, the battery lifespan will shorten. I think the answer would be to leave the charger on, whenever possible, as the charger actually stop charging the battery once it is full. Check this on your Mac: click on Apple Icon > About this Mac > System Report > Power See the ...

Might be the Apple Remote app. After the last update, I started having problems with phone staying hot and battery life draining rapidly. The Remote app had turned itself on to "stay connected". I think the phone was constantly trying to sync with my home computer. After shutting off the app, phone immediately started cooling off. Took three days to figure ...
